Health Hazard Evaluations (HHEs)
Each month we will update this page to highlight newly released final reports and information on new and emerging hazards we are evaluating. Check back often to see what we are up to!
Noise Recommendations Provided to a Gray and Ductile Foundry
Finding that employees we monitored had noise exposures greater than noise exposure limits, and most noise exposures were greater than 100 decibels, A-weighted, HHE Program investigators recommended improving acoustic barriers and treatments, maintaining equipment to eliminate rattling from loose parts, and ensuring employees wear their hearing protection properly.

Evaluation of Noise Exposures During Total Knee Replacement Surgeries
HHE Program investigators found one surgeon’s noise exposure exceeded the NIOSH REL, but all other surgical staff were below noise exposure limits. We estimated that surgeons could be overexposed to noise depending on the noise level during surgeries and length and number of surgeries in a work shift. We recommended including orthopedic surgeons in a hearing loss prevention program, using quieter surgical tools, and providing hearing protection.
